On the episode, Tweedy is persuaded by the show's characters to reunite the band for a "Unity Concert". He mostly acts as the straight man, but also sings along to a song called "Karate Chop Master", which might be your thing.

As previously reported, the Unity Concert will also feature Yo La Tengo, The Decemberists, Ginuwine, and Letters to Cleo. Yo La Tengo will play Bobby Knight Ranger—a Night Ranger cover band that wears red sweaters in the mold of the famously irascible Indiana University basketball coach.
